DHT 100623 Operations Manual
Sizing between Cat 0 – 3 is not universal between different tractor manufacturers. For most tractors, the recommended sizing is:
Post Hole Digger Model 90 – Cat 0 — Outside to Outside Width on the A-Frame 20”
Post Hole Digger Model 100 – Cat 1 & 2 — Outside to Outside Width on the A-Frame 25.5”
Post Hole Digger Model 110 – Cat 2 & 3 — Outside to Outside Width on the A-Frame 32”
All diggers come with the CAT 1 pins as whole assemblies. If you need different pins such as cat 0, 2 or 3 pins then that will be the customers responsibility to change out. The sizing between the pins on the tractor should be matched as closely as possible to the Outside to Outside width of the A-Frame to ensure a proper fit. You can use the “recommended Cat sizing” above as a general/rough guide – however this may not apply to every tractor.
Please note about lift gate delivery: You must select the $50 lift gate option if you are not able to unload the freight off the freight truck. You will not have to pay the $50 charge if you can ship to a business and you can unload the crate off the back of the freight truck with a fork lift or something similar. Shipping to a business is your best choice if possible saving you $50. These deliveries are “curb-side” only, please read the details about curb-side, lift gate and residential freight deliveries.
